Observation Maize in calico bags at 0.5mg/ml had weight loss of 7.12±1.41.
Observation Rice in plastic containers at 1.5mg/ml had the least weight loss, 1.14±0.09.
Observation Maize in plastic containers at 1.5mg/ml had weight loss of 0.75±0.21.
Intervention effect Increasing extract concentration significantly increased S. oryzae mortality.
Association Weevil mortality did not differ significantly among storage materials.
Observation S. oryzae mortality reached 8.00±0.58 in rice in plastic containers at 0.5mg/ml.
Observation S. oryzae mortality was lowest at 4.00±0.58 in rice in bagco bags at 1.0mg/ml.
Observation S. oryzae mortality did not differ between 0.5 and 1.0mg/ml in treated bagco bags or 1.0 and 1.5mg/ml in plastic containers.
Observation S. oryzae mortality in maize in plastic containers at 1.0mg/ml reached 9.00±1.53.
Observation S. zeamais mortality in maize in calico bags at 0.5mg/ml was lowest at 3.00±0.00.
Intervention effect Neem-treated materials reduced S. zeamais adult emergence relative to controls.
Intervention effect Neem-treated materials reduced S. oryzae adult emergence relative to controls.
Observation Adult emergence did not significantly differ among neem-treated storage materials.
Observation S. oryzae emergence was highest at 177.67±9.21 in bagco bags at 1.0mg/ml.
Observation S. oryzae emergence was lowest at 107.33±3.76 in rice in plastic containers at 1.5mg/ml.
Intervention effect Neem-treated materials reduced holes bored in maize and rice grain relative to controls.
Recommendation Bagco bags treated with neem at 1.5mg/ml were judged most effective for protecting stored maize and rice.
